Digital subtraction image shows (A) the image right after contrast injection into the main component of the lesion without absolute alcohol injection. After 2 seconds of contrast developing, (B) significant venous egress is shown. Radiography after a 3-mL absolute alcohol injection shows lesion without venous egress, even after 12 seconds of contrast developing; (C, D) the draining vein has been embolized.

3. Fig 2
A 28-year-old man with infiltrating venous malformation treated with seven sessions is shown (a) before the start of treatment and (b) 13 months after the end of treatment. The magnetic resonance imaging (c) shows that the lesion involves subcutaneous tissue and muscle levels of the cheek (infiltrating venous malformation), and (d) that the lesion improved significantly after the treatment.

4. Fig 3
A 32-year-old man with venous malformation of the cheek treated with 6 sessions, (a) before the start of treatment and (b) 6 months after the end of the treatment. The magnetic resonance imaging (c) shows an ill-defined margin that has an irregular interface with the surrounding tissue (infiltrating venous malformation) and that lesion infiltrates subcutaneous tissue, masseter muscle, and the tongue.
